Description

The invention relates to a control module for wireless control of at least one actuator integrated in a building installation radio network managed by a base station, which control module has a power supply with a power supply connection, a control element connection for connecting a control element that can be actuated by the user, a memory and a radio communication interface for integrating the control network installation into the control module , wherein the first radio communication interface is connected to the memory and to the control element connection in such a way that the radio communication interface, after recognizing an operating signal at the control element connection, sends a control command stored in the memory for controlling at least one actuator integrated in the building installation radio network. The invention further relates to a method for setting up and operating such a control module in a building installation radio network and a building installation radio network.

Building installation radio networks are known from the prior art. In such a building installation radio network, building technology installations are organized wirelessly as actuators. Actuators can be, for example, lamps, lights or blinds. Building technology installations that can be integrated into such a building installation radio network are also referred to as "smart products". Smart products as actuators are supplied with energy regardless of their switching status. These products have a control module with a radio receiver, via which control module the actuator is controlled depending on a received command. It is therefore controlled via the building installation network.

A building installation radio network comprises a base station for setting up and managing the participants integrated in it. Such administration includes tasks such as assigning addresses, granting access authorizations, etc.

In addition to managing the building installation radio network, the base station can also control the actuators integrated as participants in a building installation radio network. For this purpose, the base station has means to be connected to an external device, for example a smartphone, tablet or the like, which can process user input. These user inputs are transmitted to the base station, which then controls the desired actuator or actuators. The communication link for establishing a connection between the base station and smartphone, tablet or the like is required to set up the building installation radio network anyway. This type of control is used in particular with proprietary building installation radio networks. Such a building installation radio network is a network with or in which communication can only take place via special radio communication interfaces that are geared towards the purpose of a building installation radio network.

Another option for controlling actuators organized in a building installation radio network is to use control modules. These control modules are integrated as sensors in the building installation radio network. The control module is assigned an operating element that can be actuated by the user, typically a switch or button. When this control element is actuated, the control module sends a control command to an actuator assigned to the control module in the building installation radio network. Since the assignment of the control module to an actuator is problematic due to the use of dynamic addresses in a building installation radio network, such control modules are often matched by the manufacturer to a specific actuator by means of a physical address. User side can this control element can only be used for this one actuator, which is usually acquired together with the control module. Even after the initial installation, users are happy to adapt assignments between the control module and actuators to changing needs by changing such assignments or expanding them as required. However, with this configuration, this is not possible or is only possible with difficulty.

An alternative possibility of linking such a control module to the actuator integrated in a building installation network is to use mechanical contacts that the user can establish via bridges and / or switches. Alternatively, there are various types of selector switches that are attached directly to the control module.

Another approach to the use of control modules is that the control module sends a manufacturer-specific command to the base station controlling the building installation radio network, whereupon the base station processes this command and forwards it to the corresponding actuator. The same communication path as that described above is used here between the base station and an operating device external to the building installation radio network, for example a smartphone, tablet or the like. The base station acts as a converter.

A disadvantage of these controls is that an individual setup is not easily possible. Either a user is firmly bound to a system that has been coordinated by the manufacturer or a device has to be installed that can only be carried out by specially trained specialists. In addition, a mechanical device on the control module always requires the control module to be installed and removed if the control module is installed permanently in the building, which would be preferred. The provision of individual plug contacts and codings, as well as the space required for this, is also perceived as a night division.

Against the background of the prior art discussed above, the object of the invention is to propose a control module with which a simplified, individual and, in particular, manufacturer-independent device is possible, so that in principle any subscriber organized in the building installation radio network can be controlled with this control module. Furthermore, a setup method for setting up such a control module is to be proposed. Furthermore, it is an object of the invention to propose a building installation radio network with which the disadvantages shown in relation to the prior art are avoided.

This object is achieved by a generic control module mentioned at the outset, in which the control module has, in addition to the first radio communication interface provided for radio communication in the building installation radio network, a second radio communication interface that differs from the first radio communication interface for communication on a bidirectional radio communication device and one device Memory has an electronic address memory segment in which an address of the at least one actuator to be controlled can be stored.

The procedural part of the task is solved by a method having the features of claim 10 and the part of the task directed to the building installation radio network by a building installation radio network having the features of claim 14.

The control module according to the invention is designed to be integrated into a building installation radio network. In addition to the control module, at least one controllable actuator is integrated into the building installation radio network. Typically, several or even a large number of actuators are organized in the building installation radio network. Such an actuator can be an electrical blind, a Luminaire or lamp, typically designed as a so-called smart product. The control module and the controllable actuator are participants in the building installation radio network. The building installation radio network comprises a base station for administrative tasks, which are tasks such as the administration of the subscribers and addresses, any keys, etc. One of the actuators can definitely act as a base station. In a preferred embodiment, the building installation radio network is based on a low data rate network, for example a ZigBee® network (ZigBee® is a registered trademark of the ZigBee Alliance). Such networks are characterized by the fact that only a little data is transmitted and the associated subscribers require only a small amount of energy due to an appropriate implementation of the radio interface.

The control module comprises a power supply with a power supply connection that can be connected to a power supply installed on the building, via which the energy for operating the control module is drawn from the power supply installed on the building.

In one configuration, the energy supply is designed such that a phase connection and a neutral conductor of a power supply on the building side are connected to its power supply connection. The advantage of this parallel connection is that only a very small and simply constructed power supply unit is required for the power supply of the control module, so that only a small installation space is required to accommodate the same in the control module.

In another embodiment, the energy supply to the control module is designed to be connected in series with a building installation, typically an actuator. To supply power to the control module, voltage can be tapped, for example, via a load drop by means of a resistor, with which the control module is supplied with energy. Through this circuit operation of the control module is also made possible if only one power line having a phase line is available, as is the case with a large number of older power installations on the building side. It is then not necessary to re-lay power cables.

The control module can also be designed to implement both of the aforementioned configurations. For this purpose, two differently designed power supply connections for energy supply can be available in the control module, the power supply installed on the building side being connected to the corresponding power supply connection depending on the case.

The control module further comprises an operating element connection for the mechanical, typically wired connection of an operating element that can be actuated by the user. Existing operating elements, such as switches or buttons, can also be used as control elements in a double or multiple configuration in a building-side installation. The control element connection serves to receive an actuation event as a signal from the control element, which is then evaluated. According to one embodiment, the control element is designed to close a circuit when it is actuated. This can then be recognized by the control element connection. Likewise, a change in the switching position from current-carrying to non-current-carrying can also be recognized. According to a further embodiment, the use of touch-sensitive control elements for controlling a switch is also possible.

In an advantageous embodiment, the control module has means for evaluating changes in status at the control element connection, and means for monitoring whether a further change in status at the control element connection is detected after a first change in status in a defined time interval. These means are used in connection with setting up the control module in order to be able to automatically recognize in the context of a routine whether a connected control element is a button or a switch. Under a button is within this Embodiments understood a switching element in which a contact is closed during an actuation by the user and this contact opens again when the switching element is no longer actuated. Such a button is therefore monostable. In the case of a switch, a switch contact either remains permanently closed or open after actuation. The contact therefore remains in the state brought about by actuation until it is actuated again. A switch is accordingly bistable and can be designed, for example, in the form of a changeover switch. On the control module side, the type of electrical contact (s) of the control element is stored in a memory. The type of contact or contacts found - for example switches or push buttons - of the control element is used in the context of the evaluation of an actuation event recognized at the control element connection.

The control module also has an electronic memory. Control commands are stored in this memory with which actuators can be controlled in a building installation radio network. These control commands can already be stored by the manufacturer. In addition, the memory has an address memory segment in which a unique address of at least one actuator to be controlled can be stored. This can be a physical as well as a dynamic address. A dynamic address is assigned by the base station managing the building installation radio network. The addresses of individual actuators can be stored in the address memory of the control module, as can group addresses, that is to say those addresses with which a plurality of actuators organized in the network can be controlled. The address memory is preferably rewritable.

The control module also has a first radio communication interface. The control module can be integrated into a building installation radio network via this first radio communication interface. For this purpose, the first radio communication interface uses the same protocol and the same frequency as the building installation radio network and can, as soon as the control module is integrated into the building installation radio network, use a network key assigned by the base station of the building installation radio network. Via this first radio communication interface, the control module, when integrated in a building installation network, is able to query and / or receive information from the actuators integrated in the building installation radio network. In addition, the control module can use this interface to send a control command to the building installation radio network and thus to at least one actuator integrated in the building installation radio network. For this purpose, this radio communication interface has the necessary means to be able to establish bidirectional communication within the building installation radio network, for example a radio module, a controller, a high-frequency front end with antenna or the like. In this respect, within the scope of these explanations, the term radio communication interface means those components that are required for such communication. This does not mean that these components must all be combined in a single module. For example, a microcontroller that is already present in the control module can also be used to operate the radio communication interface.

The first radio communication interface, the memory and the control element connection are interconnected in such a way that when the control element connected to the control element connection is actuated, an actuation event is detected as a signal and, as a result, at least one control command for addressing at least one actuator from the memory contains the address of at least one actuator a building installation radio network integrated actuator, read out and sent via the radio communication interface. In this way, the at least one actuator assigned to the switching event when setting up the control module is controlled.

In addition to this first radio communication interface, the control module has a second one Radio communication interface. This second radio communication interface differs from the first radio communication interface. This distinction is designed in such a way that the control module can communicate bidirectionally with an external set-up device via the second radio communication interface, independently of the first radio communication interface. The differentiation between the two radio communication interfaces can lie in the use of a different protocol and / or a different frequency and / or a different network, so that the control module can communicate unidirectionally or bidirectionally with the building installation radio network via the first radio communication interface, while it can communicate with the second radio communication interface can communicate with a set-up device that is not registered in the building installation radio network. The radio communication link via the second radio communication interface is preferably also a low data rate connection in order to load the power supply of the control module with only a low energy requirement. For example, this can be implemented using a Bluetooth® protocol (Bluetooth® is a registered trademark of the Bluetooth SIG). These connection interfaces are usually present in consumer electronics products such as smartphones, tablets or the like. Devices of this type are therefore preferably used as set-up devices since they contain the components required for communication with the control module via the second radio communication interface and via a display - the display - required for setting up.

The setup device is used to set up the control module. The display functionality of such a set-up device - the display - is used to indicate the actuators that can be controlled. Furthermore, the set-up device is used to set up an association between an operating element actuation and an actuator to be actuated by this actuation, thus linking an actuating event with a control command and the address of the actuator to be actuated.

In an advantageous embodiment, there is a direct connection between the set-up device and the control module, and consequently a direct communication link without any additional devices. This can be done by means of a point-to-point connection, even in a short-range configuration. It is advantageous with such a design that no additional components, such as a base station, are required to set up a network. Another way to establish such a direct connection is to use protocols that only allow a direct connection anyway, such as Bluetooth®.

In one embodiment, a radio module of the control module is designed to operate both radio communication interfaces. For this purpose, the radio module can alternately send and receive for the first radio communication interface and for the second radio communication interface. It is advantageous that if the first radio communication interface uses the same frequency as the second radio communication interface, the radio module only has to be designed for one frequency range on the hardware side. Then the installation space required is correspondingly smaller. This can also be used advantageously for energy supply.

In another embodiment, each radio communication interface is assigned its own radio module. Then simultaneous communication via both radio communication interfaces is possible.

A control module according to the invention is set up in the following steps:

• Integration of the control module into a building installation radio network via the first radio communication interface of the control module,
• Setup of a radio communication link between the set-up device and the control module via the second radio communication interface of the control module,
• Querying information about the controllable available in the building installation radio network Actuators via the first radio communication interface of the control module, which contains information about the address of the actuators,
• Transmitting this information to the set-up device via the second radio communication interface and displaying at least part of this information on the display of the set-up device,
• Selecting at least one actuator to be controlled on the set-up device from the set of controllable actuators displayed and assigning this actuator to an actuation command that can be triggered by the operating element,
• Storage of the actuating event-actuator address linkage in the memory of the control module.

The above process steps do not necessarily have to be carried out in the order described.

In particular, it is possible to set up the radio communication link between the control module and the set-up device even before the control module is integrated into the building installation radio network.

According to this method, the control module is integrated into a building installation radio network via its first radio communication interface. In this way, the self-contained building installation radio network is opened. For this purpose, the base station is typically switched to a mode in which it searches for new subscribers within range and, if found, integrates them into the building installation radio network. This can be done automatically, for example by cyclically scanning the base station to find out which users are within range. This can also be done by a request command from the control module, sent via its first radio communication interface. Each participant receives a unique address via the administration of the building installation radio network. Initial information can also be transmitted. By integrating the control module via the first Radio communication interface enables communication between the control module and other participants in the building installation radio network, in particular the actuators that can be controlled by the control module. Furthermore, a radio communication link is set up between the control module and a set-up device, for example a smartphone, a tablet or the like, via the second radio communication interface. The control module is set up by the user via this radio communication link. The communications with the building installation radio network on the one hand and the set-up device on the other hand can differ, for example, by using a different network, a different protocol or a different frequency. It is important to ensure that both communications do not interfere with each other.

Information is queried from the building installation radio network by the control module via the first radio communication interface. For example, it can be queried which actuators organized in the building installation radio network can be controlled by the control module. The information queried thus relates at least to the address and the type of the actuatable actuator. However, the information can also contain a designation or possible states or commands with which the actuator can be controlled. The control module sends this information to the set-up device via its second radio communication interface. The control module functions to transmit this information to the set-up device in the manner of a converter.

It is also possible for the necessary data from a large number of possible actuators, which can be integrated into such a building installation radio network, in particular also from different manufacturers, to be stored in a memory of the control module. In such a case, the control module only needs to obtain the address and identity of the actuators that can be controlled via the building installation radio network.

Unless it has already been prepared by the control module, this information is further processed on the setup device and displayed to a user. A user then selects one or more actuators that can be actuated by the actuation module from the set of actuators that can be actuated. In order to simplify this process, one embodiment provides that a user initially only provisionally selects an actuator on the set-up device, for example by simply tapping it, whereupon an identification command is sent to the control module and the control module sends a corresponding control command to the provisionally selected actuator sends. As a result of this control command, the actuator is activated in accordance with the control command. This can be, for example, a brief lighting up of a lamp as a selected actuator. This option is helpful if no information is displayed on the set-up device, where which actuator is located in a building or which actuator is shown on the display of the set-up device. In a further exemplary embodiment, the preselection of the actuator can also be omitted, so that a selection of the actuator e.g. Tapping on a display directly means that the control module can directly influence the corresponding actuator. Of course, the use of an identification command is also advantageous here in order to be able to identify the desired actuator optically or acoustically in a building installation.

After a user has selected at least one actuator to be controlled and, if there are several control elements, the actuation of this actuator has been assigned to a control element, this information is sent from the set-up device to the control module via the radio communication link. The control module stores the address of the at least one actuator to be controlled in its memory. At the same time, the at least one actuator to be controlled can be briefly controlled by the control module in order to signal a successful link. This can be, for example, a brief illumination of a lamp. Should the above option of the provisional selection are not used, the activation of the selected actuator can also serve to identify the actuator.

To operate the control module to control the at least one selected actuator, the control module is informed whether the switch contact connected to the control element connection is that of a switch or that of a button. This is preferably carried out by a switch contact detection routine as a result of an evaluation of a signal present at the control element connection as part of such a routine. If the switch contact is a push button, actuation of the push button can be detected by two state changes in a predefined time interval on the control element connection. The switching of a switch, on the other hand, can be detected by only a change in state occurring in the aforementioned predefined time interval. Knowledge of the type of switch is required for the intended operation of the control module in order to be able to correctly evaluate a signal present at the control element connection.

1. (i) Zunächst wird in dem Ansteuermodul eine Zustandsänderung an dem Betätigungselementanschluss erkannt. Diese Zustandsänderung ist eine Folge einer einmaligen Betätigung des Bedienelementes. Eine Zustandsänderung kann dabei durch ein elektrisches Signal an den Bedienelementanschluss gegeben werden oder, wenn das Bedienelement einen Stromkreis schalten kann, das Schalten dieses Stromkreises.
2. (ii) Anschließend wird ansteuermodulseitig geprüft, ob nach dieser ersten erkannten Zustandsänderung in einem vorher definierten Zeitintervall eine weitere Zustandsänderung am Bedienelementanschluss detektierbar ist. Abhängig davon, ob eine weitere Zustandsänderung erkannt wurde, wird durch das Anschlussmodul ermittelt, ob es sich um einen Taster oder einen Schalter handelt: Wird eine weitere Zustandsänderung erkannt, handelt es sich um einen Taster, wird keine weitere Zustandsänderung erkannt, handelt es sich um einen Schalter. Diese Information wird dann in dem dem Ansteuermodul zugehörigen Speicher abgelegt.

In an embodiment of such a routine, it comprises two steps:

1. (i) First, a change in state at the actuating element connection is recognized in the control module. This change in state is the result of a single actuation of the control element. A change in state can be given by an electrical signal to the control element connection or, if the control element can switch a circuit, the switching of this circuit.
2. (ii) It is then checked on the control module side whether a further change in status at the control element connection can be detected after this first detected change in status in a previously defined time interval. Depending on whether a further change in status has been detected, the connection module determines whether it is a button or a switch: If another change in status is detected, if it is a button, no further change in status is detected, it is a switch. This information is then stored in the memory associated with the control module.

Of course, it is possible to carry out this method with a defined repeated actuation of the control element. The user then actuates the control element several times. The detection can then be applied analogously.

Basically, this routine is a clever way to support the user who is setting up as far as possible with the components that are already present in such a control module. The control module recognizes the characteristic behavior of the respective control element as a function of time, whereby it is possible to dispense with having to measure exact times in a complex manner and to derive calculations therefrom. It is sufficient to recognize the number of status changes in a predefined period. The system is uniquely determined by the further defined requirement for a user to have the actuating element actuated a predetermined number.

In one embodiment of this routine, the predefined time span is only a few seconds, preferably a maximum of only one or two seconds, at least not less than a typical button takes to return to its normal position.

The second radio communication interface is not necessary for the operation of the control module, even if actuators integrated in the building installation radio network can be controlled via the set-up device.

In one configuration of the setup method, the user also selects, in addition to the at least one actuator to be controlled, if an actuator can be controlled with different commands, such as a lamp being switched on and off or also dimmed at least one control command to be sent, with which the at least one actuator is to be controlled. A list of selectable control commands can be provided by the actuator, the control module and / or by the set-up device. This creates an additional opportunity to make the setup process as individual as possible.

Depending on the type of control element, the manufacturer can specify which control command is to be sent to the building installation radio network when the control element is actuated. For example, it can be provided to use an additional dimming function for a push button, which would not make sense for a switch based on its operating principle. If several commands are available with respect to a controllable actuator, at least one attribute is assigned to the control commands that can be selected by the manufacturer, which attribute corresponds to the type of control element. According to this attribute, only the control commands that make sense with regard to the connected control element are then displayed during the setup process.

In a preferred embodiment, the control element is installed together with the control module in a flush-mounted box. This avoids the need for the control module to be accommodated in a separate location. In addition, existing lines on the building side can be used for energy supply. This applies in particular if the control element is a switch or button that is already installed on the building and the switched phase is thus used to power the control module. The control module can be an independent component, switch or button, which is located behind the control element in the flush-mounted box.

In many cases, the control module will be integrated into an existing building installation by retrofitting. Before retrofitting with the control module, the control element switched a building installation, for example a lamp, by switching the power supply. Will the lamp of this lamp Replacing it with a smart lamp that has to be supplied with electricity permanently is undesirable. The installation of the control module according to the invention enables the actuator to be supplied with current on a permanent basis and, at the same time, to use the existing control element in order to control this actuator. This measure ensures a particularly simple and intuitive integration of smart luminaires into a building installation radio network, where conventionally only one luminaire could be switched due to a power cut. Existing control elements, which moreover can be operated by everyone, are used to control virtually any actuators in a building installation radio network. The existing control element can now be used to control the luminaire, which was also previously switched on when replaced by a smart luminaire, using the control module. However, this concept also enables a single control element to be changed using a double control element. One of the control elements can thus control the conventionally switched light as an actuator and with the other individual control element one or more other actuators.

A control module 1 for wireless control of an actuator 10, 11 integrated in a building installation radio network 9 comprises a power supply connection 2 and one

Control element connection 3, a memory 4 and two radio communication interfaces 5, 6. The radio communication interfaces 5, 6 comprise two radio modules, not shown in detail. The control module 1 is connected via its power supply connection 2 to a power supply 7a provided in the building and is supplied with the required energy by an energy supply, not shown, connected to the power supply connection 2. A control element 8 is connected to the control element connection 3. In the exemplary embodiment described, this control element 8 is a button. The control module 1 and the button serving as control element 8 are installed in a flush-mounted box.

The control module 1 is integrated into the building installation radio network 9 via the first radio communication interface 5. In addition to the control module 1, the building installation radio network 9 comprises two actuators 10, 11, which can be controlled via the building installation radio network 9, and a base station 12 which manages the building installation radio network 9. The base station 12 has the appropriate resources, such as, for example, to carry out the tasks of managing the building installation network 9 Address memory, means for integrating subscribers into the building installation radio network 9 and the like. The two actuators 10, 11 and the base station 12 also have their own energy supply, each of which is connected to a power supply 7b, 7c, 7d provided in the building. In this exemplary embodiment, the two actuators 10, 11 are smart lights. A base station 12 has assigned a network address to the two actuators 10, 11 for communicating or controlling them within the building installation radio network 9.

To set up the control module 1, it has the second radio communication interface 6. Via this second radio communication interface 6, communication via a wireless communication link 13 with a set-up device 14 is possible. In the present exemplary embodiment, the set-up device 14 is a smartphone.

If the control module 1 is to be set up, it is first typically installed in a flush-mounted box behind the control element 8 and its power supply connection 2 is connected to the power supply 7a installed in the building. The control element 8 is connected to its control element connection 3. Since the control module 1 is energized after the connection of the power supply connection 2 to the power supply 7a, it is integrated into the building installation radio network 9. The building installation radio network 9 described in the exemplary embodiment operates according to the ZigBee® standard. In order to integrate the control module 1 into the building installation network 9 managed by the base station 12, a corresponding command is sent to the base station 12 or a button on the base station 12 is actuated manually in order to put the base station 12 into a scan mode in order to network-seeking devices within range. In the course of this routine, the control module 1 is found and integrated into the building installation radio network 9. The control module 1 thus receives its own network address.

If the control module 1 is integrated in the building installation radio network 9, it asks information about the controllable actuators 10, 11, to which information belongs in particular information regarding the type of the actuator, its control options and its network address. The type of control is carried out by querying attributes defined by the manufacturer.

Furthermore, the communication link 13 is set up with the setup device 14 from the setup device 14 to the control module 1 via the second radio communication interface 6. This communication path 13 is provided as a radio communication path, the communication path 13 being a Bluetooth® connection in the exemplary embodiment described. The establishment of this communication link 13 can be queried before Information from the building installation radio network 9 takes place simultaneously with this or also afterwards.

If the control module 1 has queried the information from the building installation radio network 9 and the communication link 13 has been set up, this information is transmitted via the communication link 13 to the set-up device 14 and displayed to a user on a display. The user then selects one or more actuators 10, 11 to be controlled - in this exemplary embodiment only one actuator 10 - from the set of actuators 10, 11 which can be controlled. The setup device 14 then sends a corresponding command via the communication link 13 to the control module 1, whereupon the control module 1 writes the address of the actuator 10 to be controlled in its memory 4 together with a control command assigned to an actuating event of the control element 8. Thus, in the course of the installation, the control element 8 is linked to a control command and the actuator 10 to be controlled, so that when the control element 8 is actuated, the actuator 10 is controlled in accordance with the actuation event carried out.

As part of the setup of the control module 1, a routine is carried out to determine whether the control element 8 is a button or a switch. To recognize this, a user setting up the control module 1 is asked, for example by a prompt symbol on the display, to actuate the control element 8 once. With reference to the Figures 2a and 2b The following status change patterns can be recognized by the control module 1 at the control element connection 3:
Figure 2a shows the characteristic behavior of a switch. When requested, the actuating element is actuated once by a user. The relevant change in state 15 in this example is the closing of a circuit and can be seen on the control element connection 3 of the control module 1. The detection of the change in state 15 at time t ₁ begins with respect to its length, predefined time interval T. On the control module side, it is then checked whether a further change in state at the control element connection 3 can be detected within this time interval T, the duration of which ends at time t ₂ . Since a switch remains in its state after actuation, no further state change is registered in the time interval T by the control element connection 3. The determined switch type definition, here: switch, is then stored in the memory 4 of the control module 1. When selecting the control command, the switch type is taken into account during the setup.

Figure 2b shows the characteristic switching behavior of a button in the course of the routine described above. When the control element 8 is actuated by the user, a circuit is closed. This is recognized on the control module side at the control element connection 3 as a change of state 16 at the time t ₁ . The predefined time interval T begins at this time. Since the actuation of the button 8 comprises not only the pressing but also the releasing, the circuit opens after a certain time. This opening is recognized as a second state change 17 by the control element connection 3. In contrast to the state change behavior of a switch (see Figure 2a ) two state changes 16, 17 in the time interval T can be seen on the control element connection 3. If a button is recognized as control element 8, it is stored in memory 4.

The control element recognition routine can be carried out as part of the setup of the control module 1 and is linked to the control element depending on the type of the control element 8 determined - switch or button - with the control command applicable to the control of the intended actuator 10. After the setup of the control module 1 has ended, it is switched to its operating mode.

In order to operate the control module 1, a user actuates the control element 8. There is then an on the control element connection 3 Signal recognizable. The control module 1 recognizes this signal, reads the control command associated with this actuating event in the memory 4 and the address of the actuator 10 to be controlled, and controls the selected actuator 10 via the first radio communication interface 5. The actuator 10 to be activated receives the activation command, processes it and changes its state accordingly.

The invention has been described using an exemplary embodiment. Without leaving the applicable scope of protection, described by the claims, numerous further configurations result for a person skilled in the art to realize the inventive idea, without these having to be explained in detail in the context of these statements.
